I have just recently bought a used iBook G4 and a Linksys WRT54G v8 router. I also have an iMac G4 800 that is wired to the router. Both machines are running the latest version of OSX. I have a DSL modem connected to the router so I can share an internet connection. Without the iBook communicating to the router, the iMac uses the internet with no problems. I also eliminated the router and connected it straight from the modem into the iMac and it worked great. But when the iBook's airport is communicated with the router, every 2 minutes the router drops the connection and the internet does not work on either machine. I have installed the lastest firmware for the router and even cloned both computers' MAC addresses. Nothing has made a difference. Thank you for your help.
